1. The furnace area must be kept clear and free of combustible materials, gasoline and other flammable vapors and liquids.
2. Insulating materials may be combustible. The furnace must be kept
free and clear of insulating materials. The furnace area must be
examined when installed in an attic or other insulated space or
when insulation is added to be sure that the insulation material has
been kept away from the furnace.
3. The furnace needs air for combustion in order to operate properly
and safely. Do not block or obstruct air openings on the furnace, air
openings to the area where the furnace is installed, or spaces
around the furnace.
4. Follow the instructions exactly as shown on the OPERATING
INSTRUCTION LABEL on the furnace or the “START-UP AND
SHUTDOWN INSTRUCTIONS” section of this manual when lighting the furnace or turning the furnace off.
5. Should the gas supply fail to shut off or if overheating occurs, shut
off the gas valve to the furnace before shutting off the electrical supply.
6. Do not use this furnace if any part has been under water. A flooddamaged furnace is extremely dangerous. Attempts to use the furnace can result in fire or explosion. A qualified service agency
should be contacted to inspect the furnace and replace all gas controls, control system parts, electrical p art s that have been wet or the
furnace if deemed necessary.
7. NEVER. . .S tore flammable materials of any kind near your furnace.
Gasoline, solvents, and other volatile liquids should be stored only
in approved containers outside your home. These materials vaporize easily and are extremely dangerous.
8. NEVER. . .Store cleaning materials near your furnace. Materials
such as bleaches, detergents, powdered cleansers, etc., can cause
corrosion of the heat exchangers.
9. NEVER. . . Use the area around your furnace as a storage area for
items which could block the normal flow of air. This flow of air is
required for ventilation of the various furnace components.

FIRE OR EXPLOSION HAZARD
This furnace is designed and approved for use with Natural Gas and
(LP) Propane Gas ONLY. DO NOT BURN ANY LIQUID FUEL OR
SOLID FUEL IN THIS FURNACE.
Burning any unapproved fuel will result in damage to the furnace heat
exchanger, which could result in Fire, Personal Injury, and/or Property
Damage.
INSTRUCTIONS FOR EXAMINING THE
FURNACE INSTALLATION
It is the owner’s responsibility to ensure that an annual inspection of the
entire heating portion of the unit is made by a qualified service agency.
Examine the furnace as outlined below in steps “1 - 8” before each
heating season. Use Figures 1 - 6 for visual reference.

1. Examine the heat exchanger, vent pipe, combustion air passages,
vent connectors and chimney to be sure they are clear and free of
obstructions.
2. Examine the vent pipe making sure it is firmly in place, that it slopes
slightly upward and is physically sound without holes and all of the
connections are secure.
3. Examine the return-air duct connections to make sure they are
physically sound, sealed to the furnace casing, and the ducts terminate outside the space containing the furnace.
4. Examine the furnace casing making sure the physical support is
sound without sagging, cracks or gaps. Examine the furnace base
making sure it is physically sound without cracks, gaps or sagging
and has a good seal.
5. Examine the furnace casing for obvious signs of deterioration.
6. Examine the burner flames to make sure they are in good adjustment. Refer to the pictorial sketch shown in Figure 7 as a comparison to the actual flame.
FIGURE 7: Burner Flame Drawing (Upflow Configuration Shown)
7. Examine and replace external air filters as needed to make sure
they are not blocked, and proper airflow is provided to the furnace.
8. Examine any installed accessories or system components such as
evaporator coils to insure proper operation, drainage of condensate, and that there is no water leakage or damage to the furnace
or any components.

START-UP AND SHUTDOWN
INSTRUCTIONS
Read the Instructions Below Before Trying to Start the
Furnace!
If you do not follow these instructions exactly, a fire or explosion may
result causing property damage, personal injury, and/or loss of life.
HOW YOUR GAS FURNACE WORKS
Your furnace is a very easy appliance to take for granted. Season after
season, it sits there in your home, keeping you warm and comfortable.
For this reason, you may never have given much thought to the way
your furnace operates. In order to get the safest and most efficient operation from your furnace, you should understand how your furnace does
its job.
When you set your thermostat to provide more heat in your home, you
are starting the heating cycle of the furnace. First, the inducer motor
starts to purge the heat exchanger of any remaining gases. Next, the
hot surface ignitor glows and after a warm-up period the gas valve
opens and ignition occurs. A short time later, the blower starts and distributes the warm air throughout the home. When the temperature setting on your thermostat is reached, the gas valve closes, the main
burners are turned off, and the blower continues to run until the remaining warm air in the system is distributed. When the blower stops, the
heating cycle has ended.
1. This appliance does not have a pilot. It is equipped with an ignition
device which automatically lights the burner. Do not try to light the
burner by hand.
2. BEFORE OPERATING; smell all around the appliance area for gas.
Be sure to smell next to the floor because some gas is heavier than
air and will settle on the floor.
3. Use only your hand to push the gas control switch to the ON position. Never use tools. If the switch will not operate by hand, don’t try
to repair it, call a qualified service technician. Force or attempted
repair may result in a fire or explosion.
4. Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and
to replace any part of the control system and any gas control, which
has been under water.
